Abstract

A system of non-reactive components for moving or for moving and stretching plastic tissue that exerts a relatively constant dynamic force over a variety of distances and geometries, that is easily adjustable, and is self-adjusting. This system includes a “button anchor system” for moving tissue, particularly including deep fascia and muscle layers of the abdominal or thoracic cavity wall, in surgical, post surgical, and post traumatic reconstruction where the wound margins are beyond a distance that permits normal re-approximation. Button anchor assemblies allow re-approximation of severely retracted abdominal wall and full thickness thoracic wounds where a closure force is required to be applied to the sub-dermal layers. Systems of this invention allow for such a force to be applied and externally controlled during treatment.

Claims

1. A system for moving tissue comprising:

(a) at least one non-reactive force applying component; and

(b) at least one anchor for attachment to the tissue, the anchor comprising

(i) a first slot sized to allow the force applying component to freely pass through the anchor, and

(ii) a second slot sized to capture the force applying component without knotting or tearing the force applying component and formed to provide adjustable attachment of the force applying component; and

(c) at least one anchor pad coupled to the at least one anchor and adapted to distribute force across an area of the tissue, the pad comprising a pad slot corresponding to the first slot of the anchor.

2. The system of claim 1, further comprising an anchor tail.

3. The system of claim 2, wherein the anchor tail further comprises adhesive and an engaging loop.

4. The system of claim 2 wherein the anchor tail further comprises polyurethane foam.

5. The system of claim 2 wherein the anchor tail further comprises fabric.

6. The system of claim 5 wherein the fabric is elastic and conforms to the skin surface.

7. The system of claim 3 wherein the loop comprises wire.

8. The system of claim 3, wherein the anchor further comprises a hook having a ramp for guiding the loop of the anchor tail up and into a depression of the anchor.

9. The system of claim 1, wherein the second slot of the anchor is a metered tension, locking slot, with a shape, length and size such that the slot captures the force applying component but allows the component to migrate if tension exceeds a pre-determined level.

10. The system of claim 1 wherein the force applying component comprises elastomer.

11. The system of claim 10 wherein the elastomer comprises silicone.

12. The system of claim 1 wherein the tension is adjustable within an elastic limit of the force applying component.

13. The system of claim 1 wherein the force applying component is adapted to deform to be released from the anchor upon application of a predetermined force.

14. The system of claim 1 wherein at least two anchors are adapted to be attached to the tissue on opposite sides of a wound or incision.

15. The system of claim 14 wherein the at least two anchors secure at least one force applying component and wherein the force applying component passes through tissue and fascia.

16. The system of claim 1 wherein the anchor pad further comprises a compressible material.

17. The system of claim 1 wherein the anchor pad further comprises silicone.

18. The system of claim 1, the anchor pad further comprising a skin contacting surface having antimicrobial properties.

19. The system of claim 1 wherein the anchor further comprises apertures and the anchor pad further comprises projections that pass through the apertures and couple the anchor pad to the anchor.

20. The system of claim 1 wherein the anchor and anchor pad are adhesively bonded.

21. The system of claim 1 wherein the anchor and anchor pad are integral.

22. The system of claim 1, wherein the anchor further comprises finger grips.

23. The system of claim 1 wherein the tissue to be moved is healthy tissue.

24. A system for moving tissue comprising:

(a) at least one non-reactive force applying component; and

(b) at least one anchor for attachment to the tissue, the anchor comprising an opening sized to allow the force applying component to freely pass through the anchor, wherein the anchor distributes force applied to the tissue and bolsters a perimeter of a transcutaneous opening through with the force applying component passes.

25. The system of claim 24 wherein the anchor further comprises

(i) a first slot sized to allow the force applying component to freely pass through the anchor, and

(ii) a second slot sized to capture the force applying component without knotting or tearing the force applying component and formed to provide adjustable attachment of the force applying component.

26. The system of claim 24 further comprising at least one anchor pad.

27. The system of claim 26 wherein the at least one anchor pad is coupled to the at least one anchor and comprises a pad slot corresponding to the first slot of the anchor.

28. The system of claim 24, further comprising at least one anchor tail.

29. The system of claim 28 wherein the at least one anchor tail comprises adhesive for attachment to the tissue and wherein the anchor tail is coupled to the anchor.

30. An anchor assembly for attachment to tissue to transmit force for moving the tissue, the anchor assembly comprising:

(a) at least one anchor for attachment to the tissue, the anchor comprising

(i) a first slot sized to allow a force applying component to freely pass through the anchor,

(ii) a second slot sized to capture the force applying component without knotting or tearing the force applying component and formed to provide adjustable attachment of the force applying component, and

(b) an anchor tail attachable to the anchor and comprising adhesive for attachment to the surface of the skin.

31. The anchor assembly of claim 30, wherein the anchor tail further comprises a loop.

32. The anchor assembly of claim 30, further comprising an anchor pad.

33. The anchor assembly of claim 32, further comprising a slot sized to allow a force applying component to freely pass through the anchor.

47. The method of claim 32 wherein the adjusting tension further comprises referring to a quantitative tension indication feature of the force applying component.

34. An anchor assembly for attachment to tissue to transmit force for moving the tissue, the anchor assembly comprising:

(a) at least one anchor for attachment to the tissue, the anchor comprising

(i) a first slot sized to allow a force applying component to freely pass through the anchor,

(ii) a second slot sized to capture the force applying component without knotting or tearing the force applying component and formed to provide adjustable attachment of the force applying component, and

(iii) a hook for coupling the anchor tail to the anchor; and

(b) an anchor pad adapted to distribute force across an area of the tissue comprising a pad slot corresponding to the first slot of the anchor; and

(c) an anchor tail comprising adhesive for attachment to the surface of the skin and a loop for engaging the anchor.

35. The anchor of claim 34 wherein the anchor tail further comprises polyurethane foam.

36. The anchor of claim 34 wherein the anchor tail further comprises elastic fabric.

37. The anchor of claim 34 wherein the loop of the anchor tail comprises wire.
